Be it known that I, FRANK L. VVIOKHAM, a citizen of the United States,residing at Lennon, in the county of Genesee and State of Michigan, haveinvented certain new and useful Improvements in Masons Tools, of whichthe following is a specification.

This invention relates to an improved tool for use in connection withcertain trades, such as stone masons, brick masons, and the like, in thespreading, shaping, and smoothing of plastic materials.

A further and important object of this invention is the provision of animproved tool embodying a trowel arrangement, and

i a shaping member adjustably associated therewith.

A further object of this invention is the provision of an improved toolof the above mentioned character, which may be utilized for the quickand efficient performance of work by stone or brick masons, in thepointing, beading, jointing, and tucking of various classes of work.

Other objects and advantages of this invention will, of course, beapparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, andwherein similar reference characters designate corresponding partsthroughout the several views.

Figure 1 is a side elevation of the improved tool, showing the partsthereof in operative relation.

Figure 2 is a plan view of the trowel arrangement of the improved tool.

Figure 3 is a transverse cross sectional view, taken through a portionof the improved tool.

Figure l is a fragmentary view, partly in section, showing the manner inwhich the improved tool may be successfully used in conjunction with theshaping or beading of r plastic material at the joint of walls and likestructures.

In the drawing, wherein for the purpose of illustration is shown but thepreferred embodiment of this invention, the letter A genericallyindicates the improved tool, which may embody the trowel arrangement B,and improved oint shaping tool C.

Referring to the trowel arrangement B, the same preferably comprises theflat sub 5 stantially V-shaped blade 10, the side mar- Serial No.600,753.

ginal edges 11 of which are disposed in con verging relation toward thepointing tips 12. A handle 15 is provided, preferably being formed rigidor integral therewith with blade 10, including the upwardly inclinedhand engaging portion 16, relatively broader than/thick, to provide aconvenient grasp for the operator in order to facilitate use of thetool. A hooked end portion 17 is preferably formed at the rear end ofthe handle portion 16, being reduced with respect thereto, andpreferably circular in cross section. This hook shaped portion 17preferably includes the arcuate or curved part 19, which extendsupwardly above the handle portion 16, and the straight line portion 20,the axis of which is parallel to blade 10, and having a tapered surfacewhich gradually converges to a point 21, the portion 20 being disposedupwardly of the handle portion 16 to-pro vide a suflicient spaceintermediate the same and the hand engaging portion 16 to accommodatethe hand of the operator.

The shaping member 0, or beader, as it may appropriately be called, isadapted for cooperation upon the tapered surface portion 20 of thetrowel B, and preferably includes the cylindrical shaped body portion25, providing a tapered opening 26 which extends longitudinallytherethrough, for the wedge shaped reception of the straight line andtapered surfaced portion 20, substantially as is illustrated in Figure 3of the drawing. Radial portions 28, 29 and 30 preferably extend from thecylindrical body portion 25, and are arranged entirely longitudinally ofthe header member These radial extensions are provided with differentsurfaces for effecting different beads or shaped depressions in thejoints of plastic material. Thus, it is preferred to provide the convexarcuate surface 32 upon the extension 28; concave surface 33 ofrelatively short radius extending longitudinally of the extension 29;and convex surface 24: of relatively larger radius than the surface 33,provided upon the radial extension 30.

Referring to the use of the improved tool A, it is to be noted that theblade 10 thereof may be used in the ordinary and well known manner forspreading, shaping, or smoothing of plastic materials. The taperedhooked end portion 20 may be utilized independent of the shaping member13, as

for tucking, that is, the fine marking of plastic materials, such asplaster walls, to provide artificial blocks or bricks, or the laying outof similar arrangements. In this connection,'the point- 21 is used. Inpointing up or shaping of the joints or layers of plastic materialintermediate blocks or bricks, the member C will find an effective useto quickly facilitate an operation. As illustrated in Figure 4:, thebeader C when used upon the trowel B for providing concaved exteriorsurfaces in plastic joints, is so arranged that the convex surface 82 ofthe lateral extension 28 may be moved along the plastic material 40intermediate blocks or bricks 41. In this position, the joint shapingmember C is, of course, rigidly afiixed upon the tapered straight axisend ortion 20 against accidental rotation incident to the wedge actionthereon. Similarly, beads may be provided in a plastic joint byutilization of the concaved shaping surfaces 33 and 34, which may beselectively used merely by adjustment of the beading member C upon thesupporting portion 20 of the tool A.

i From the foregoing description of this invention, it can. readily beunderstood that the improved tool is capable of selective use inconnection with pointing, beading, jointer, or tucking. It is to benoted that beader C and the portion 17, are disposed upwardly of thehand engaging portion 16, and not below, thus facilitating the use ofthe trowel member B, and in no wise interfering with the effective graspof the same by an operator.

Various changes in the shape, size and arrangement. of parts may be madeto the form of invention herein shown and described, without departingfrom the spirit of this invention or the scope of the claims.

I claim:

1. As an article of manufacture, a shaping tool comprising a.substantially cylindrical shaped body portion, and radial projectionsextending therefrom and, longitudinally thereof provided upon theirextremities with beading and shaping surfaces of various kinds.

2. As an article of manufacture, a tool for shaping of plastic materialscomprising a cylindrical body portion provided with a tapered openingextending axially therethrough, and radial extensions on said bodyportion arranged longitudinally thereof provided upon their outerlongitudinal surfaces with concaved and convex surfaces of variousshapes and formations.

3. As an article of manufacture, a tool comprising a handle portionincluding a relatively straight upper end having a surface tapered to apoint, and a member including various surfaces for the shaping ofplasticmaterial having a tapered bore therein for detachable andadjustable reception of said tapered handle end.
